Abstract
A projectile fuze includes a detonator carrier having a safety position and an armed position; a pin having a blocking position in which it holds the detonator carrier in the safety position and a releasing position in which the pin allows the detonator carrier to move into the armed position; a spring urging the pin into the releasing position; a pyrotechnical delay element exposed to hot propellant gases for causing ignition and combustion of the delay element; and a pin-supporting component maintaining the pin in the blocking position against a force of the spring. The pin-supporting component is held in the pin-maintaining state by the delay element until combustion thereof, whereby the pin is allowed to move into the releasing position upon combustion of the delay element.
Claims6
A fuze for a projectile adapted to be accelerated by gas pressure obtained by propellant combustion, comprising
- (a) a detonator carrier having a safety position and an armed position;
- (b) a pin having a blocking position in which said pin holds said detonator carrier in said safety position thereof and a releasing position in which said pin allows said detonator carrier to move into said armed position;
- (c) a spring urging said pin into said releasing position;
- (d) a pyrotechnical delay element exposed to hot propellant gases for causing ignition and combustion of the delay element by the propellant gases;
- and
- (e) a pin-supporting component maintaining said pin in said blocking position against a force of said spring;
- said pin-supporting component being held in the pin maintaining state by said delay element until combustion thereof, whereby said pin is allowed to move into said releasing position upon combustion of said delay element.
A projectile adapted to be accelerated by gas pressure obtained by propellant combustion, comprising
- (a) a projectile body;
- (b) an explosive payload accommodated in said projectile body;
- (c) a fuze accommodated in said projectile body and comprising
- (1) a detonator carrier having a safety position and an armed position;
- (2) a pin having a blocking position in which said pin holds said detonator carrier in said safety position thereof and a releasing position in which said pin allows said detonator carrier to move into said armed position for detonating said explosive payload;
- (3) a spring urging said pin into said releasing position;
- (4) a combustible pyrotechnical delay element;
- and
- (5) a pin-supporting component maintaining said pin in said blocking position against a force of said spring;
- said pin-supporting component being held in the pin maintaining state by said delay element until combustion thereof, whereby said pin is allowed to move into said releasing position upon combustion of said delay element;
- and
- (d) means defining a passage leading to said delay element for admitting hot propellant gases to said delay element to cause ignition and combustion thereof.
